I bought this product to give to my wife about 2 years ago (the sleeve was red colored then). She really has enjoyed it. Before a camping trip, we course grind around 8 tbsp of beans for each pot full of coffee we want to make, then vacuum seal them in individual packs. Heat water to 195~198°F, add coffee and water to press, let steep for ~8 minutes, slowly press it down, and pour...good everytime. Washup is very easy (just remove the sleeve to keep it from getting wet, rest is easy enough to dry).
